PURPOSE: An eco cement wall is provided to efficiently construct an environmentally-friendly underground wall structure by employing a multi-functional, environmentally-friendly material, freely using a single- or multi-axis auger, and adding a reactant for reduction of toxicity into cement. CONSTITUTION: An eco cement wall is constructed as follows. The ground is bored with one of a single-axis auger, a double-axis auger, a triple-axis auger, a quadruple-axis auger, and a quintuple-axis auger and, at the same time, individual or mixed materials are injected from the leading end and/or side of the auger to be inserted into the ground or mixed with the soil. The auger is drilled to the designated depth and carries out surging. The auger is pulled out from the ground and, at the same time, individual or mixed materials are injected from the leading end and/or side of the auger to be inserted into the ground or mixed with the soil. Therefore, a consolidated body in a wall shape is formed in the ground. |
